The changing weather conditions, including sudden wind gusts, were not effectively reassessed before continuing the operation. Dynamic risk assessment was not actively updated to reflect the increased risk created by the changing environmental conditions. Situational awareness of changing operating and environmental conditions was not effectively maintained during the task. Communication between the Assistant Driller and floor crew was not sufficiently effective to ensure a shared understanding of the risks and controls. Load control was not adequately maintained, allowing the sucker rod to deviate from its intended path following the sudden block movement. Red-zone control and verification of safe operating conditions were not effectively maintained throughout the operation. Signs of fatigue and reduced vigilance may have affected the ability to identify and respond to changing conditions in a timely manner.
